I have been playing with Babolat RPM Blast on the mains and Gamma TNT on the crosses of my Wilson Steam 99s at around 53 lbs but just wasn't lasting long enough, so I began looking for more durable strings. I strung Moto as the mains and Gamma TNT2 on crosses all at 53 lbs. I was looking for a more durable string for the extremely open (16 x 15) string pattern that also wouldn't hurt my elbow. They played well with some feel, control and enough power, but still didn't have the durability I was looking for. Moto popped before TNT within two or two and a half weeks of stringing it, playing with it for a few hours each day. It did not injure my elbow, and played well while it lasted. All in all, it was a nice string and would last longer in a racket with a more closed pattern and someone who doesn't hit the ball so heavy.
